Eligibility

Inclusion Criteria:

• Males and females, 18 years of age or older.

• Only 1 prior treatment course with visilizumab (or placebo in a blinded visilizumab study).

• Response (as defined in parent protocol) of intravenous steroid-refractory ulcerative colitis (IVSR-UC) disease to visilizumab or placebo.

• Symptomatic worsening (ie, an increase of =3 points in MTWSI score) from the subject's best response on the parent study, an MTWSI score of =9, sustained for at least 2 assessments performed at least 1 week apart, and a confirmatory MTWSI =8 within 1 day prior to randomization.

• CD4^+ T-cell count = 200 cells/mcL at screening for this protocol, or = 80% of the subject's screening baseline count prior to enrollment on the parent study.

• Mayo assessment (including flexible sigmoidoscopy) performed by a trained, blinded evaluating physician within 2 weeks prior to randomization.

• Adequate contraception from the day of consent through 3 months after the last dose of study drug.

• Negative serum pregnancy test.

• Negative Clostridium difficile test.

• Signed and dated informed consent, and Health Insurance Portability and Accountability Act (HIPAA) if applicable.

Exclusion Criteria:

• UC requiring immediate surgical, endoscopic, or radiologic interventions.

• White blood cell count less than 2.5 x 10^3/mcL; platelet count less than 150 x 10^3/mcL; or hemoglobin less than 8 g/dL.

• Active, medically significant infections, particularly those of viral etiology, eg, known cytomegalovirus (CMV) colitis. This includes any incidence of opportunistic infections within the past 12 months.

• Live vaccination within 6 weeks prior to randomization.

• Significant organ dysfunction, including cardiac, renal, liver, CNS, pulmonary, vascular, gastrointestinal, endocrine, or laboratory abnormality, history of myocardial infarction, coronary artery disease, congestive heart failure, or arrhythmias within 6 months prior to consent.

• History of lymphoproliferative disorder (LPD) or malignancy other than nonmelanoma skin cancer or carcinoma in situ of the cervix that has been adequately treated within the past five years.

• Seropositive for infection with human immunodeficiency virus (HIV-1), hepatitis B virus (HBV) surface antigen, or hepatitis C virus (HCV).

• Pregnancy or nursing.

• Treatment with any other UC salvage drugs (including but not limited to infliximab or another anti-TNF-a drug, cyclosporine, tacrolimus [FK506], adalimumab, thalidomide, or another experimental agent), or therapies (surgery, pheresis, affinity columns) since the first course of treatment with study drug in the parent visilizumab study.

• Treatment with any other investigational drug or therapy within 60 days prior to randomization.

• Nontherapeutic levels of chronic antiseizure medications in subjects with a history of seizures.

• Any condition that, in the investigator's opinion, makes the subject unsuitable for study participation.
